women are more likely to be hospitalized and are at higher risk of death and complications from flu, including swine flu and seasonal flu, than the general population. As scary as that sounds, experts say that most pregnant women who become ill with H1N1 swine flu will not have a serious problem. If you are pregnant, here's what you need to know.
But if you know what the symptoms are and how to take precautions, you can avoid these problems and stay healthy.
What Is the Flu?
It's a very contagious disease caused by the influenza virus. People tend to catch it most often in the fall and winter. It comes on fast and strong, spreading through your upper respiratory tract and sometimes invading your lungs.
It can happen when the flu virus enters your lung or when you get a bacterial infection during the course of the illness. Pneumonia can make you quite ill and may send you to the hospital.
It can cause chills, fever, chest pains, and sweating. You might have a cough with green or bloody mucus. You could notice a faster pulse, and your lips or nails might have a bluish tint because of a lack of oxygen. Other symptoms include shortness of breath and sharp pains in your chest when you take a deep breath. Seniors may only notice a pain in the belly.
